The Quinn family drove 228 miles in 4 hours at a constant rate. Which equation can be used to determine how far they traveled each hour?

Answers

Answer 1

Answer: What can be used on this is the distance over time formula, so what you,do is divide 228 by 4 to get the distance traveled in one hour. And 288/4=57. So they traveled 57 mi in one hour. Hope this helped.

Answer 2

Answer: Okay, so all you would have to do is find the unit rate, and to do that, you would divide 4 INTO 228, (228 divided by 4), which would be 57, so they drive 57 miles PER HOUR.
I hope I helped! =D
